Letters PateatNo. 91,890, dated Jgzme v29, 1869.

The Schedule 4referred to in lthese Letters Patent and making part of the same.

To all whoml lit may concern Be it known that I, JAMES B. WILLIAMS, of Gla-stenbury, county of Hartford, and State of Connecticut, have invented certain new ,and useful Improvements in the Manufacture of Evaporating-Pans; and to enable others skilled in the art to make andl use. the same, I will proceed to describe its construction, referring to the drawings, in which the same letters indicate like parts in each ofthe figures.

First, the nature' of this invention consists in so connecting-or compressing 4the edges ofthe corrugated bottoni into the wood sides, as to eectually secure it from leakage.

Second, it further consists 'of set-oli` bolts, secured to the bottom of the pan, so as to allow the holesl for their reception to be made a short distance from the groove that receives the bottom, to prevent leakage that would oceurwhere the hole is made close to or' connected to the groove for the bottom ofthe pan.

Third, it further consist-s in striking up caps of the exact. size and shape of the corrugations, for the purpose ot' capping the ends of the corrugations, which are cutaway alternately, first one, then the other, even with the bottom of the pan, to allow the liquid or sirup to pass from one end ot' the pan to the other.

Fourth, it further consists in boring a hole from the 'inside surface. of the sides of the pan, nearone end and just abovethe bottom of the pan, about the sizeof the inside diameter ofthe faucet, and aboutone-tburth the thickness ot' the plank, and a hole about'thesize of the outside diameter ot' said faucet from a centre directly opposite, to intersect with the rst, to allow the faucet to be turned up firmly and closely against the shoulder, at the junction ofthe two size holes, the obvject of which is to secure against the possibilityof d are wood sides, into vwhich are formed grooves or i depressions, k, for the reception of the edges of Vthe bottom and'its corrugations.

e are caps, made or struck up in a die the exact size ofthe corrugations, for the purpose of producing uniformty of shape to the corrugations where they are cut away Hush with the bottom, and to secure straightedges to the bottom.

fis a hole, bored in the side plank, from the inside thereof, about one-fourth of its thickness, near one end of the pan,.and in diameter about the size of the inside diameter of the faucet, and a second l1ole,.f, about the diameter of the outside of the faucet from a point on the outside, directly opposite of the first, to allow the end ofthe faucet to -be turned up firmly and closely against theshodlder g, at the junction of the two holes, thereby preventing the .liability of leakage around the edge of the bottom near the faucet.

71. are set-oli bolts, the strap@ of which is secured to' the under side ot the pan. The set-oi tallows the hole to be bored a short distancev below the groove k, formed in the side, for the reception of the bottom, the object of which is toprevent leakage from said groove around the bolt, as in the old way, where the bolt-holevis connected with the groove.

These pans are made ordinarily about nine feet wide, and the wood is yprotected from the tire by walls builtv up about twelve or fifteen inches from the sides of the pan for the support of lthe pan, and between which the fire or heat is brought in contact with the under side of thev pan, to facilitate evaporation.

I believe I have thus shown the nature, construction, andadvantage of this invention, so as to enable others skilled in the art to make and use the same.

What I claim, therefore, and desire to secure by Letters Patent, is

1. Form-ing grooves, k, formed in the sides d, in combination with a corrugated bottom, coustructed'aud arranged substantially as described.

2. The set-off bolts 7L, in combination with a corrugated bottom, b, and sides d, substantially as and for the vpurpose described.

3. The caps e, constructed as described, in combination wit-h the corrugated' bottom b and .sides d, substantially as and forthe purpose'described.

4. Forming a union ot' the faucet with the. corrugated pan through theside d, substantially in the manner and for the purpose described.
